Test box structure

The outer shell is made of imported PVC plastic sheet, which is softened at high temperature and then cooled by a special mold to form a shape. The joints between the sheets are milled into 90 degree right angles, and then filled with plastic welding wire melted by a high-temperature welding gun. The cooled welds are more firm. The inner liner is made of imported PP plastic sheet, with a maximum temperature resistance of 80 degrees. The joints of the entire box are smooth and flat, the box structure is compact, and the appearance is shiny,

The temperature and humidity inside the box are controlled by an external temperature and humidity air conditioning cabinet to create a specified temperature and humidity environment that enters the box and circulates inside the box. A set of air conditioning system is designed for the equipment, which includes a refrigeration system, a heating system, and a humidification system. The air conditioning system is manufactured to meet the temperature and humidity requirements of the test. After being stirred evenly in the mixing chamber between the inner and outer shells of the equipment, it enters the box and inputs a certain concentration of mixed gas. The flow rate is controlled to reach the specified range, and the concentration can be detected by various gas concentration detectors. The equipment heats up quickly and the temperature and humidity are evenly distributed. The heating and humidification element adopts titanium metal heating tubes, which are corrosion-resistant and have a long service life. The box door is made of tempered glass, making it easy to open and close. Using corrosion-resistant silicone rubber seal to ensure that gas does not overflow. The design of the sample frame structure follows national standards and can also use hooks, which have a large load-bearing capacity and are easy to place the test samples. After the gas comes out of the steel cylinder, it is depressurized and then controlled by a corrosion-resistant solenoid valve to enter the mixing box through a flow meter. Afterwards, it enters the diversion pipeline at the bottom of the box together with the temperature and humidity air in the air conditioning cabinet, and passes evenly through the box. Equipped with over temperature protection and low water level warning to ensure safe use.

The refrigeration system of the equipment is installed at the bottom of the equipment, mainly for cooling and dehumidification purposes.

The equipment control system is designed on the right side of the box and is easy to operate. The specially designed gas filtration device can quickly and effectively filter the residual gas inside the box after the experiment is completed, and the residual gas will not cause pollution to the atmosphere, making it easy to operate.
